Lighting device for an aerial work platform

Abstract

A battery powered lighting device is configured to be attached to lift bucket having sidewalls and an upper lip extending from uppermost portions of the sidewalls. The lighting device includes a main housing, a securing member, and a main light mounted to the main housing and located to illuminate areas outside of the lift bucket. The main housing includes a first securing surface and an upper housing portion, with the upper housing portion configured to be located above the upper lip of the lift bucket with the first securing surface engaged against a surface of the lift bucket. The main light is mounted to the main housing to move between a lower position wherein the main light is positioned below the upper housing portion and an upper position wherein the main light is positioned above the upper housing portion.

What is claimed is: 
     
       1. A battery powered lighting device configured to be releasably attached to an aerial work platform in the form of a lift bucket having sidewalls and an upper lip extending from uppermost portions of the sidewalls, the lighting device comprising:
 a main housing comprising:
 a battery mount configured to mount a battery to power the lighting device, 
 a first clamp surface configured to engage a sidewall or the upper lip of the lift bucket, 
 an upper housing portion configured to be located above the upper lip of the lift bucket with the first clamp surface engaged against a sidewall or the upper lip of the lift bucket, and 
 a forward portion extending forward and upward from the first securing surface to the upper housing portion to form a rearwardly opening u-shaped channel; 
 
 a clamp member comprising a second clamp surface, the clamp member mounted to the upper housing portion to move between an open position wherein a sidewall or the upper lip of the lift bucket can be inserted between the first and second clamp surfaces and a clamping position wherein the sidewall or the upper lip is clamped between the first and second clamp surfaces with the upper housing portion located above the lip of the lift bucket; and 
 a main light mounted by a pivot mount to the main housing to pivot relative to the main housing about a first axis between a lower position wherein the main light is positioned below the upper housing portion and an upper position wherein the main light is positioned above the upper housing portion; 
 wherein the main light is mounted to the forward portion by the pivot mount to pivot relative to the main housing about the first axis between the lower and upper positions. 
 
     
     
       2. The lighting device of  claim 1  wherein the main light is further mounted to move relative to the main housing between at least a forward facing position and a sideward facing position with the main light located in the lower position and with the main light located in the upper position. 
     
     
       3. The lighting device of  claim 1  wherein the main light is further mounted by another pivot mount to pivot relative to the main housing about a second axis between a forward facing position and a sideward facing position.
